Deye LV LiFePO4 100Ah SE-G5.1 Pro-B ESS Battery - CEC approved

The Deye SE‑G5.1 Pro‑B is a modular 48V energy storage module designed for residential and light commercial solar systems. Deye SE‑G5.1 Pro‑B Low Voltage Battery Module uses lithium iron phosphate (LiFePO₄) chemistry for inherent safety and long life while providing 5.12 kWh of nominal energy per unit. Its compact design fits into standard installations and pairs well with compatible Deye inverters. The design of the SE-G5.1 Pro-B supports flexible system growth. Multiple modules can be connected in parallel to scale up total capacity without major reconfiguration, making it adaptable as energy use changes over time. This scalability helps balance daily energy storage needs. Every module incorporates a smart battery management system (BMS) that monitors performance and provides protection. The system is built to run across a broad temperature range and uses natural air cooling, reducing moving parts and potential maintenance. Remote monitoring and firmware updates are also supported for easier management. Clean Energy Council (CEC) Approved: What's This? Purchasing this entitles you to the Cheaper Home Batteries Program.
